PILL-MAKING DEVICE.

SPECIFICATION forming part of Letters Patent No. 299,258, dated May 27,1884. Application filed March 5, 1884. (No model.)

To all whom, it may concern.-

Be it known that I, EDWARD B. PATTER- sON, of Detroit, in the county ofVayne and State of Michigan, have invented new and useful Improvementsin Pill-Making Devices; and I do hereby declare that the following is afull, clear, and exact description thereof, reference being had to theaccompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvements inmechanism to be employed in the manufacture of pills.

It has hitherto been the practice in the manufacture of pills to employa flat bed of the proper size, across one end of which was provided aseries of semicircular recesses or corrugations, with a hand-tool fiatupon one side, while upon the other it was provided with a similarseries of semicircular recesses or corrugations, so arranged that whenin use the corrugations of the bed were coincident to the corrugationsupon the hand-tool, and the recess thus formed was circular. The massfrom which the pills were made was rolled upon the flat bed by the useof the flat side of the hand-tool into what is technically termed pipes,and as it is necessary that the pills should be of equal size andweight, and easily rolled into the round form from the pipes, the sizeof the latter is required to equal in diameter the area of thecylindrical recess formed by the juxtaposition of the corrugations ofthe bed and hand-tool when in place; hence the size of the pipes is ofimportance, and hithertoit has been the practice to gage them by meansof calipers, which is a slow process, and, unless care is used, somewhatuncertaim It is to remedy this defeet in the process of making pillsthat is the object of my invention, which is so constructed thatadjustable guideways are employed, by means of which, withoutdifficulty, accuracy is obtained in the size of the pipes, and byadjusting the guideways different sizes, as may be required, are readilymanufactured.

Figure l is a perspective View of the ordinary bed and corrugationsprovided with my improvement, shown as in position for'making thesmallest size pills, and in dotted lines for the largest size, theintermediate sizes being obtained by the proper adjustment between thesetwo extremes. Fig. 2 is a perspective of the hand-tool.

In the accompanying drawings, which form a part of this specification, Arepresents the fiat bed, provided with a series of semicircularcorrugations, B. Each side of the bed is provided with an inclined way,0, the lower point of which is at the front of the bed, and extending onparallel lines upward to the rear of such bed. Guideways D are provided,the upper edges of which are parallel to the plane of the flat bed,while the lower edges of the same are upon inclined planes of the sameinclination as those of the inclined ways upon which such guideways run.A setscrew, E,'entering the front end of the bed and passing through thecross-tie at the front end of the guideways, affords the means foradjusting the position of the latter. Of course, any other mechanicaland known device for effecting this adjustment would come within thespirit of my invention.

From the above description the advantages to be derived from the use ofmy improvement are so obvious that a further description thereof isdeemed unnecessary.

What I claim as myinvention is l. The bed of a pill-making device,provided with inclined ways upon which guideways can be adjusted tovarying heights with relation to such bed, substantially as described.

2. In combination with the bed of a pillmaking device, provided withinclined ways upon its sides, the guide-bars herein described,substantially as and for the purposes specified.

3. In combination with the bed and guideways of apill-mal ing device,constructed substantially as described, means for adjusting saidguideways with relation to the plane of the bed, substantially as andfor the purposes set forth.
